Description

Wireless communication method, storage medium and terminal device

This application claims priority to the Chinese patent application filed with the China Patent Office on November 18, 2022, with application number 202211448766.7 and invention name “Wireless Communication Method, Storage Medium and Terminal Device”. The entire contents of the above patent are incorporated into this application by reference.

Technical Field

The present application relates to the field of communication technology, and in particular to a wireless communication method, a storage medium, and a terminal device.

Background technique

In a wireless fidelity (Wi-Fi) communication system, in order to discover network devices, the terminal device will perform periodic full-channel scanning to scan whether there are accessible network devices around. When the terminal device scans and accesses the Wi-Fi network provided by a network device, the terminal device can store the authentication information when accessing the network device; when the terminal device disconnects from the Wi-Fi network and re-scans the network device, the terminal device can obtain the authentication information corresponding to the network device from the stored record to initiate authentication to the network device, so that the terminal device can automatically reconnect to the Wi-Fi network provided by the network device.

However, the current scanning cycle of terminal devices is relatively long. For example, the scanning cycle of a terminal device in standby mode can be as long as 300 seconds, resulting in poor terminal device reconnection efficiency. In addition, full-channel scanning requires the terminal device to switch back and forth on multiple Wi-Fi channels for scanning, resulting in high terminal device scanning power consumption, which affects terminal device performance.

Summary of the invention

The embodiments of the present application provide a wireless communication method, a storage medium, and a terminal device, which identify Wi-Fi devices scanned by a terminal device when it has historically accessed a Wi-Fi network through stored Wi-Fi fingerprints and cell identifiers, so that when the terminal device is not connected to a Wi-Fi network, the Wi-Fi scanning mode is switched through the Wi-Fi fingerprint and the cell identifier, thereby reducing the Wi-Fi scanning power consumption of the terminal device and improving the efficiency of the terminal device re-accessing the Wi-Fi network.

In a first aspect, the present application provides a wireless communication method, including: a terminal device performs a Wi-Fi scan in a first scanning mode; a matching relationship between a Wi-Fi device scanned by the terminal device and a Wi-Fi device in a stored first Wi-Fi fingerprint satisfies a first matching condition; and the terminal device performs a Wi-Fi scan in a second scanning mode, wherein a scanning interval of the first scanning mode is greater than a scanning interval of the second scanning mode.

In an embodiment of the present application, the first scanning mode is used to indicate a Wi-Fi scan based on cycle 001, and the second scanning mode is used to indicate a Wi-Fi scan based on cycle 002. The Wi-Fi devices scanned by the terminal device when it historically accesses the Wi-Fi network are identified by the stored first Wi-Fi fingerprint. In the process of the terminal device performing Wi-Fi scanning in the first scanning mode, for example, when the terminal device is disconnected from the Wi-Fi network and needs to rescan for networking, when the Wi-Fi devices scanned by the terminal device include Wi-Fi devices scanned when the terminal device historically accessed the Wi-Fi network, it can be determined that the current terminal device is closer to the location when it historically accessed the Wi-Fi network, and the terminal device can shorten the scanning time, increase the Wi-Fi scanning frequency, and thereby improve the efficiency of the terminal device re-accessing the Wi-Fi network.

In a possible implementation of the first aspect, the first Wi-Fi fingerprint is determined by the following method: the terminal device accesses a first Wi-Fi signal provided by a first Wi-Fi device; acquires multiple second Wi-Fi devices scanned by the terminal device; and determines the first Wi-Fi fingerprint based on the first Wi-Fi device and the multiple second Wi-Fi devices.

In the embodiment of the present application, the first Wi-Fi device is used to represent the target network device, and the second Wi-Fi device is used to represent the associated network device. When the terminal device scans and accesses the Wi-Fi network provided by a certain network device, all network devices scanned by the current terminal device are recorded. Among all network devices, the network device connected to the current terminal device is regarded as the first Wi-Fi device, and the network device not connected is regarded as the second Wi-Fi device, and the first Wi-Fi fingerprint is generated based on the first Wi-Fi device and multiple second Wi-Fi devices.

In a possible implementation of the first aspect, the first Wi-Fi fingerprint is determined by the following method: the terminal device accesses a first Wi-Fi signal provided by a first Wi-Fi device at a first time; acquires multiple second Wi-Fi devices scanned by the terminal device at the first time; and determines the first Wi-Fi fingerprint based on the first Wi-Fi device and the multiple second Wi-Fi devices.

In the embodiment of the present application, the first time is used to indicate the time when the terminal device accesses the first Wi-Fi signal provided by the first Wi-Fi device. The Wi-Fi fingerprint for the first Wi-Fi device can be collected at the time when the terminal device accesses the first Wi-Fi signal provided by the first Wi-Fi device.

In a possible implementation of the first aspect, the method further includes: the terminal device disconnecting the first Wi-Fi signal provided by the first Wi-Fi device at a second time; and using the multiple Wi-Fi devices scanned by the terminal device at the second time as second Wi-Fi devices to update the first Wi-Fi fingerprint.

In the embodiment of the present application, the second time is used to indicate the time when the terminal device disconnects the first Wi-Fi signal provided by the first Wi-Fi device. The Wi-Fi fingerprint for the first Wi-Fi device can also be collected when the terminal device disconnects the first Wi-Fi signal provided by the first Wi-Fi device.

In a possible implementation of the first aspect, the matching relationship between the Wi-Fi device scanned by the terminal device and the Wi-Fi device in the stored first Wi-Fi fingerprint satisfies the first matching condition, including: the Wi-Fi device scanned by the terminal device includes all or part of the plurality of second Wi-Fi devices.

In the embodiment of the present application, when the above-mentioned matching relationship satisfies the first matching condition, indicating that the Wi-Fi devices scanned by the terminal device include the second Wi-Fi device scanned when the terminal device historically accessed the first Wi-Fi device, it can be determined that the current terminal device is closer to the location when the terminal device historically accessed the first Wi-Fi signal provided by the first Wi-Fi device.

In a possible implementation of the first aspect, the method further includes: corresponding to the matching relationship between the Wi-Fi device scanned by the terminal device and the Wi-Fi device in the stored first Wi-Fi fingerprint not satisfying the first matching condition, the terminal device performing a Wi-Fi scan in a first scanning mode.

In an embodiment of the present application, when the above-mentioned matching relationship does not meet the first matching condition, it means that there is no first Wi-Fi device that has been historically connected around the current location of the terminal device, and the terminal device cannot automatically access the Wi-Fi network. Therefore, a Wi-Fi scan is performed using a cycle 001 with a longer interval scanning time, thereby reducing the scanning power consumption of the terminal device.

In a possible implementation of the first aspect, the terminal device performs Wi-Fi scanning in a first scanning mode, including: when the Wi-Fi devices scanned by the terminal device include the first Wi-Fi device, the terminal device accesses a first Wi-Fi signal provided by the first Wi-Fi device; and when the Wi-Fi devices scanned by the terminal device do not include the first Wi-Fi device, determining whether a matching relationship between the Wi-Fi devices scanned by the terminal device and the Wi-Fi devices in a stored first Wi-Fi fingerprint satisfies a first matching condition.

In a possible implementation of the first aspect, the terminal device performs Wi-Fi scanning in the second scanning mode, including: corresponding to the Wi-Fi device scanned by the terminal device including the first Wi-Fi device, the terminal device accesses a first Wi-Fi signal provided by the first Wi-Fi device.

In a possible implementation of the first aspect, the Wi-Fi channels supported by the Wi-Fi scanning of the terminal device include multiple first Wi-Fi channels; and the first scanning mode includes: performing Wi-Fi scanning based on the multiple first Wi-Fi channels.

In an embodiment of the present application, the multiple first Wi-Fi channels may be a combination of any Wi-Fi channels that can be used by the terminal device in the 2.4 GHz and 5 GHz operating frequency bands, and the multiple first Wi-Fi channels may also be all Wi-Fi channels supported by the terminal device for Wi-Fi scanning. The first scanning mode is used to indicate that Wi-Fi scanning is performed based on cycle 001 and using multiple first Wi-Fi channels. Since the terminal device is not connected to the Wi-Fi network when using the first scanning mode, using multiple first Wi-Fi channels (full channel scanning mode) in cycle 001 can improve the efficiency of the terminal device scanning to Wi-Fi devices.

In a possible implementation of the first aspect, a Wi-Fi channel through which the terminal device accesses the first Wi-Fi signal provided by the first Wi-Fi device is a second Wi-Fi channel, wherein the second Wi-Fi channel is any one of the multiple first Wi-Fi channels; and the second scanning mode includes: performing Wi-Fi scanning based on the second Wi-Fi channel.

In the embodiment of the present application, the second Wi-Fi channel is used to represent the target channel. After determining that the current terminal device is close to the location when the first Wi-Fi signal provided by the first Wi-Fi device was historically accessed, the terminal device can switch from multiple first Wi-Fi channels (all-channel scanning mode) to the second Wi-Fi channel (single-channel scanning mode), reducing scanning power consumption and ensuring scanning and searching for the first Wi-Fi device.

In a possible implementation of the first aspect, the terminal device performs the Wi-Fi scan in the second scanning mode, including: acquiring a first scanning number of the terminal device performing the Wi-Fi scan based on the second Wi-Fi channel; corresponding to the first scanning number not exceeding the first threshold, the terminal device performs the Wi-Fi scan in the second scanning mode; corresponding to the first scanning number exceeding the first threshold, the terminal device performs the Wi-Fi scan in the first scanning mode.

In the embodiment of the present application, when the terminal device does not scan the first Wi-Fi device, and the first scanning number of the second Wi-Fi channel is When the first threshold is not exceeded, it may indicate that the user's terminal device may be moving in a direction close to the first Wi-Fi device, and the terminal device continues to use the second scanning mode to perform Wi-Fi scanning. When the terminal device does not scan the first Wi-Fi device, and the first scanning number of the second Wi-Fi channel exceeds the first threshold, it indicates that the user's terminal device may be moving in a direction away from the first Wi-Fi device, thereby making it impossible for the terminal device to automatically access the Wi-Fi network provided by the first Wi-Fi device in a short period of time. The terminal device switches from the second scanning mode to the first scanning mode for Wi-Fi scanning, thereby improving the efficiency of the terminal device scanning Wi-Fi devices and reducing the scanning power consumption of the terminal device.

In a possible implementation of the first aspect, before the terminal device performs Wi-Fi scanning in the first scanning mode, the following steps include: a matching relationship between a cell identifier received by the terminal device and a cell identifier in a stored first cell identifier set satisfies a second matching condition; and the terminal device performs Wi-Fi scanning in the first scanning mode.

In the embodiment of the present application, the cell identifier set is used to represent multiple cell identifiers collected when the terminal device accesses and disconnects the first Wi-Fi signal provided by the first Wi-Fi device.

In a possible implementation of the first aspect, the terminal device performs Wi-Fi scanning in a first scanning mode, including: a matching relationship between a cell identifier received by the terminal device and a cell identifier in a stored first cell identifier set does not satisfy a second matching condition; and the terminal device performs Wi-Fi scanning in a third scanning mode; wherein a scanning interval of the third scanning mode is greater than a scanning interval of the second scanning mode.

In the embodiment of the present application, the third scanning mode is used to indicate that Wi-Fi scanning is performed based on cycle 003.

In a possible implementation of the first aspect, the first cell identifier set is determined by the following method: a terminal device accesses a first Wi-Fi signal provided by a first Wi-Fi device; multiple first cell identifiers received by the terminal device are acquired; and the first cell identifier set is determined based on the multiple first cell identifiers.

In a possible implementation of the first aspect, the first cell identifier set is determined by the following method: the terminal device accesses a first Wi-Fi signal provided by a first Wi-Fi device at a first time; obtains multiple first cell identifiers received by the terminal device at the first time; and determines the first cell identifier set based on the multiple first cell identifiers.

In a possible implementation of the first aspect, the method further includes: the terminal device disconnecting the first Wi-Fi signal provided by the first Wi-Fi device at a second time; and using the multiple cell identifiers received by the terminal device at the second time as the first cell identifier to update the first cell identifier set.

In an embodiment of the present application, when a terminal device accesses or disconnects from a Wi-Fi network provided by a first Wi-Fi device, the terminal device may simultaneously collect the Wi-Fi fingerprint and the cell identifier of the terminal device, and store the correspondence between the cell identifier, the Wi-Fi fingerprint, and the first Wi-Fi device currently accessed by the terminal device to generate a feature information table, so that the terminal device may further switch the scanning mode of the terminal device by detecting changes in the cell identifier.

In a possible implementation of the first aspect, the method further includes: a scanning interval of the third scanning mode is greater than or equal to a scanning interval of the first scanning mode.

In the embodiment of the present application, the scanning interval relationship of each scanning mode is the third scanning mode>the first scanning mode>the second scanning mode.

In a possible implementation of the first aspect, the method further includes: a Wi-Fi channel on which the terminal device performs Wi-Fi scanning in a second scanning mode is a second Wi-Fi channel; when a first scanning number of Wi-Fi scanning performed by the terminal device based on the second Wi-Fi channel exceeds a first threshold; corresponding to the terminal device being in a mobile mode, the terminal device performs Wi-Fi scanning in the second scanning mode; corresponding to the terminal device being in a stationary mode, the terminal device performs Wi-Fi scanning in a third scanning mode.

In the embodiment of the present application, the mobile mode is used to indicate a mobile state, and the stationary mode is used to indicate a stationary state.

Detailed ways

The illustrative embodiments of the present application include but are not limited to a wireless communication method, a storage medium, and a terminal device.

In order to facilitate those skilled in the art to understand the solutions in the embodiments of the present application, the relevant contents that may be involved in the present application are first explained below.

(1) Wi-Fi access process

As shown in FIG. 1 , the wireless fidelity communication system includes a terminal device 11 and a network device 12 . The terminal device 11 can connect to a Wi-Fi network through the network device 12 .

The terminal device 11 can be any electronic device that supports wireless network connection, including but not limited to: mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR)/virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (PDA) or special cameras (such as SLR cameras, card cameras), etc. For example, as shown in Figure 1, the terminal device 11 is a mobile phone.

The network device 12 may be a wireless switch in a wireless network, including but not limited to: a wireless router, a wireless network card, a modem, etc. For example, as shown in FIG. 1 , the network device 12 is a wireless router.

In some embodiments, the process of the terminal device 11 accessing the Wi-Fi network provided by the network device 12 generally includes three stages: scanning, authentication, and association. In conjunction with FIG1 , the following mobile phone is used as an example of the terminal device 11, and the wireless router is used as an example of the network device 12, and the related processes of the three stages are explained as follows:

First, the mobile phone can obtain the Wi-Fi network provided by the wireless routers around the mobile phone through Wi-Fi scanning. Among them, according to the different Wi-Fi scanning methods of the mobile phone, Wi-Fi scanning can be further divided into active scanning and passive scanning.

Active scanning: When scanning, the mobile phone actively sends a probe request frame on the Wi-Fi channel. The probe response frame sent by the surrounding wireless routers is used to find the corresponding wireless router providing the Wi-Fi network. The probe response frame includes but is not limited to: Service Set Identifier (SSID), Basic Service Set Identifier (BSSID), encryption and authentication methods and other wireless network information.

Passive scanning: The mobile phone discovers the Wi-Fi network provided by the surrounding wireless routers by listening to the beacon frames sent regularly by the wireless routers. It can be understood that the wireless routers regularly broadcast Beacon frames on the Wi-Fi channel, and the Beacon frames include wireless network information such as SSID, BSSID, encryption and authentication methods.

Secondly, after the mobile phone obtains the Wi-Fi network provided by the surrounding wireless routers through Wi-Fi scanning, it initiates an authentication request to the corresponding wireless router based on the Wi-Fi network.

For example, a mobile phone obtains the Wi-Fi network provided by the surrounding wireless routers through Wi-Fi scanning, and displays the SSID of the scanned Wi-Fi network on the display screen; if the user needs to join a wireless network, he can click the corresponding SSID on the display screen, and the mobile phone responds to the user's click operation and pops up a password input window; after the user enters the password and other information in the password input window, he clicks the connect button, and the mobile phone responds to the user's operation on the connect button and sends an authentication request frame to the wireless router according to the password and other information entered by the user.

For another example, a mobile phone obtains a Wi-Fi network provided by a surrounding wireless router through Wi-Fi scanning, and detects that the Wi-Fi network is a Wi-Fi network that the mobile phone has accessed in the past. The mobile phone can then obtain the password information of the Wi-Fi network that was historically accessed from the historical records, and automatically send an authentication request frame to the wireless router.

After receiving the authentication request from the mobile phone, the wireless router performs authentication according to the information carried in the authentication request, obtains the authentication result, and returns the authentication result to the mobile phone.

Finally, after the mobile phone receives the authentication result returned by the wireless router, if the authentication result is authentication passed, it sends an association request to the wireless router. In response to the association request, the wireless router sends an association response to the mobile phone to notify the mobile phone that the association is successful. At this point, the mobile phone is connected to the Wi-Fi network provided by the wireless router.

(2) Wi-Fi channels and Wi-Fi operating frequency bands

In some embodiments, the Wi-Fi operating frequency band can be 2.4 GHz and 5 GHz, or 6 GHz in the sixth generation Wi-Fi (Wi-Fi 6), without specific limitation.

In some embodiments, the Wi-Fi device can work in both 2.4 GHz and 5 GHz frequency bands. For example, if the Wi-Fi module of the Wi-Fi device supports Dual Band Dual Concurrent (DBDC), the Wi-Fi device can work in two frequency bands simultaneously. Among them, the Wi-Fi device supporting DBDC integrates two complete channels, including two complete baseband processors and two RF front ends. Among them, the Wi-Fi device is used to indicate a wireless router or a mobile phone.

For example, a wireless router that supports DBDC can send out 2.4GHz and 5GHz network signals at the same time, that is, it provides two Wi-Fi networks, one Wi-Fi network is in the 2.4G frequency band, and the other Wi-Fi network is in the 5G frequency band.

For another example, a mobile phone that supports DBDC can simultaneously connect to a 2.4G Wi-Fi network and a 5G Wi-Fi network. The two Wi-Fi networks can be provided by the same network device or by two network devices. For example, a mobile phone that supports DBDC can simultaneously connect to a 2.4G Wi-Fi network and a 5G Wi-Fi network of wireless router A, or can separately connect to a 2.4G Wi-Fi network of wireless router A and a 5G Wi-Fi network of wireless router B.

In other embodiments, the Wi-Fi device can only work in one frequency band in the same period, that is, it can only work in the 2.4G frequency band or the 5G frequency band in the same period. For example, wireless router A supporting DBDC works in both the 2.4G frequency band and the 5G frequency band, providing a 2.4G frequency band Wi-Fi network and a 5G frequency band Wi-Fi network, while the Wi-Fi module of the mobile phone can only work in one frequency band, so the mobile phone can only connect to the 2.4G frequency band Wi-Fi network or the 5G frequency band Wi-Fi network, and cannot connect to both 2.4G and 5G frequency bands of Wi-Fi networks at the same time.

The following uses the 2.4 GHz and 5 GHz operating frequency bands as examples to explain Wi-Fi channels.

There are available Wi-Fi channels on each operating frequency band. Taking China as an example, as shown in Figure 2, there are 13 available Wi-Fi channels on the 2.4G frequency band, namely channel 1 to channel 13; the available Wi-Fi channels on the 5G frequency band include channel 36, channel 40, channel 44, channel 48, channel 52, channel 56, channel 60, channel 64, channel 149, channel 153, channel 157, channel 161 and channel 165.

In some embodiments, a DBDC-supporting Wi-Fi device may broadcast or monitor Beacon frames on multiple Wi-Fi channels available in both 2.4G and 5G frequency bands. For example, a wireless router A supporting DBDC may broadcast Beacon frames on multiple Wi-Fi channels available in both 2.4G and 5G frequency bands, and accordingly, a mobile phone supporting DBDC may switch back and forth between multiple Wi-Fi channels available in both 2.4G and 5G frequency bands to monitor Beacon frames; or, for example, a mobile phone supporting DBDC may send a probe request frame on multiple Wi-Fi channels available in both 2.4G and 5G frequency bands.

It can be understood that the mobile phone can obtain the Wi-Fi network provided by the wireless router through Wi-Fi scanning; in other embodiments, mobile phones and other terminal devices that support the Wi-Fi network sharing function can enable the Wi-Fi network sharing function to enable other mobile phones and other terminal devices to obtain the shared Wi-Fi network through Wi-Fi scanning, that is, mobile phones and other terminal devices that support the Wi-Fi network sharing function can also serve as the above-mentioned network devices to provide Wi-Fi networks.

In some embodiments, the scanning time for the mobile phone to perform Wi-Fi scanning can be determined by the working mode of the mobile phone.

For example, as shown in FIG3 , a schematic diagram of a process for determining a scanning time is shown, which specifically includes the following steps:

S301: The mobile phone is not connected to the Wi-Fi network.

In some embodiments, when it is detected that the mobile phone is not connected to the Wi-Fi network, the mobile phone can scan the surrounding wireless routers to access the Wi-Fi network through the Wi-Fi scanning method. Further, the scanning time of the Wi-Fi scan can be determined by detecting the screen light mode of the mobile phone.

S302: Detect whether the mobile phone screen is on.

In some embodiments, when it is detected that the mobile phone is not in the bright screen mode, it can indicate that the mobile phone is not used by the user, the mobile phone is in standby mode, and the user has low demand for the Wi-Fi network. The mobile phone can use a longer scanning time for scanning, for example, the first scanning time is 60 seconds, the second scanning time is 120 seconds, the third scanning time is 180 seconds, and the fourth scanning time is 240 seconds. Subsequently, in order to reduce the power consumption of the mobile phone, the mobile phone usually extends the scanning time of the Wi-Fi scan, for example, the scanning time is always 300 seconds after the fifth scan.

It is understandable that a mobile phone can usually determine whether there is a connectable Wi-Fi network around it through the previous Wi-Fi scans. If the mobile phone fails to connect to a Wi-Fi network in the previous Wi-Fi scans, it is determined that there is no available Wi-Fi network around the current mobile phone, and the scanning time of the Wi-Fi scan is extended to reduce power consumption. Therefore, the scanning time of the previous scans can be adjusted in different usage scenarios.

In other embodiments, when it is detected that the mobile phone is in the bright screen mode, the scanning time can be further determined by the static mode of the mobile phone, and the process jumps to step S303.

S303: Detect whether the mobile phone is stationary.

In some embodiments, when it is detected that the mobile phone is in the bright screen mode but not in the static mode, it can indicate that the user is using the mobile phone and the user has a demand for the Wi-Fi network, such as the user using a mobile phone or other terminal device while walking. The mobile phone can adjust the scanning time, for example, the first scanning time is 20 seconds, the second scanning time is 40 seconds, the third scanning time is 80 seconds, and the fourth scanning time is 160 seconds. If the mobile phone does not connect to the Wi-Fi network in the first few Wi-Fi scans, the scanning time of the Wi-Fi scan is then extended, for example, the scanning time for the fifth and subsequent times is always 300 seconds.

In other embodiments, when it is detected that the mobile phone is in the bright screen mode and in the static mode, it can indicate that the user is using the mobile phone and the user has a high demand for the Wi-Fi network. For example, when the user places the mobile phone on the desktop and uses the mobile phone to play music, watch movies, cast movies, etc., the mobile phone is in static mode, and the mobile phone needs to connect to the Wi-Fi network to play music, watch movies, cast movies, etc., that is, the user has a high demand for the Wi-Fi network. The mobile phone can use a shorter scanning time for scanning, for example, the first three scanning times are 10 seconds, and the fourth to sixth scanning times are 30 seconds. If the mobile phone is not connected to the Wi-Fi network in the first few Wi-Fi scans, the scanning time of the Wi-Fi scan is then extended, and the scanning time for the seventh and subsequent times is always 300 seconds.

In some embodiments, if the working mode of the mobile phone is constantly changing, but there is no Wi-Fi network that the mobile phone can access around the mobile phone, such as no wireless router around the mobile phone, or the password information of the wireless router used for authentication around the mobile phone cannot be obtained by the user. However, since the working mode of the mobile phone is constantly changing, the mobile phone will adjust the scanning time according to the detection results. At the same time, since there is no Wi-Fi network that the mobile phone can access around the mobile phone, and the scanning time of the first few times after each adjustment is shorter, the scanning power consumption of the mobile phone increases.

In some embodiments, if the working mode of the mobile phone is relatively fixed, and there are Wi-Fi networks that the mobile phone can access around the mobile phone, such as wireless routers that have been accessed in the past around the mobile phone, or password information used for authentication of wireless routers around the mobile phone can be obtained by the user, etc. However, due to factors such as unstable wireless router signals or external obstructions, the mobile phone failed to scan the wireless router in the first few scans, and then the mobile phone will extend the scanning time of the Wi-Fi scan. At the same time, because there are Wi-Fi networks that the mobile phone can access around the mobile phone, the mobile phone cannot quickly scan the wireless router to connect to the Wi-Fi network, which reduces the efficiency of the mobile phone connecting to the Wi-Fi network.

In some embodiments, in order to ensure that the mobile phone can scan all surrounding wireless routers during the above-mentioned Wi-Fi scanning process, the mobile phone usually adopts a full-channel scanning method, that is, switching among the 13 Wi-Fi channels in the 2.4G frequency band or multiple Wi-Fi channels in the 5G frequency band to perform Wi-Fi scanning. It can be seen that when the full-channel scanning method is adopted, the scanning power consumption of the mobile phone is relatively large.

To solve the above problem, when the terminal device is in use, when the terminal device scans and connects to a Wi-Fi network provided by a certain network device, all network devices scanned by the current terminal device are recorded. Among all network devices, the network device connected to the current terminal device is used as the target network device, and the network devices not connected are used as associated network devices. A Wi-Fi fingerprint is generated based on the target network device and the associated network devices, and the target network device is identified by the Wi-Fi fingerprint. At the same time, the Wi-Fi network connected to the terminal device and the target network device is recorded. Channel, use the Wi-Fi channel as the target channel for the target network device.

In this way, when the terminal device subsequently disconnects from the Wi-Fi network and needs to re-scan for the network, when the real-time network devices scanned by the terminal device include any one or more associated network devices in the Wi-Fi fingerprint, it can be determined that the current terminal device is close to the target network device, and the terminal device can shorten the scanning time and increase the Wi-Fi scanning frequency, thereby improving the efficiency of the terminal device scanning the target network device to re-access the Wi-Fi network. At the same time, when it is determined that the current terminal device is close to the target network device, the terminal device can obtain the target channel of the corresponding target network device from the historical records, and switch from the full channel scanning mode to a separate target channel scan, so that the terminal device does not need to switch back and forth between multiple Wi-Fi channels in the full channel scan, thereby reducing the scanning power consumption of the terminal device.

In some embodiments, the target network device is a network device that the terminal device has accessed historically, and the multiple associated network devices are multiple network devices scanned by the terminal device when it has accessed the target network device historically. The multiple network devices scanned by the terminal device when it has accessed the target network device historically may include network devices that the terminal device has not accessed, and may also include network devices that the terminal device has accessed historically, that is, the associated network devices may be network devices that the terminal device has not accessed, and may also be network devices that the terminal device has accessed historically.

For example, when the terminal device is not connected to a Wi-Fi network and is performing Wi-Fi scanning, two network devices that have been connected in the past are scanned at the same time, such as target network device 13 and target network device 14. Since the Wi-Fi network signal of target network device 13 is stronger, the terminal device can preferentially access the Wi-Fi network provided by target network device 13. At this time, target network device 14 can be used as an associated network device of target network device 13.

The following uses the mobile phone 10 as an example of a terminal device, and explains the process of generating a Wi-Fi fingerprint in combination with a scenario in which the mobile phone 10 is connected to a network device.

In some embodiments, as shown in FIG. 4 , when mobile phone 10 is located at position 10A, the Wi-Fi scanning area of mobile phone 10 is area 10A1; when mobile phone 10 is located at position 10B, the Wi-Fi scanning area of mobile phone 10 is area 10B1; network device 01 is the target network device of mobile phone 10.

It can be understood that network device 01 is a network device that mobile phone 10 has accessed in the past, that is, mobile phone 10 stores password information for authenticating network device 01. When mobile phone 10 scans network device 01, mobile phone 10 can obtain password information from the historical record to initiate authentication to network device 01, and then mobile phone 10 can automatically reconnect to the Wi-Fi network provided by network device 01; or network device 01 can also be a network device that mobile phone 10 has not accessed in the past, but is a network device that the user wants to connect to, that is, the user knows the password information for authenticating network device 01. When mobile phone 10 scans network device 01, the user can enter the password information through the network connection prompt pop-up window displayed by mobile phone 10 to initiate authentication to network device 01, so that mobile phone 10 can connect to the Wi-Fi network provided by network device 01.

As shown in FIG4 , when the user carries the mobile phone 10 at position 10A, the mobile phone 10 can scan network devices 01, 02, 03, 04 and 05 through full channel scanning. The mobile phone 10 can automatically initiate a request to the network device 01 for network connection; or the user can select the SSID corresponding to the network device 01 and enter the password information through the network connection prompt pop-up window displayed by the mobile phone 10 to initiate a request to the network device 01 for network connection.

After the mobile phone 10 accesses the Wi-Fi network provided by the network device 01, the network device information A obtained by the mobile phone 10 at the position 10A through the full channel scan is recorded. At this time, the network device information A includes network devices 01, 02, 03, 04 and 05, and the network device 01 accessed by the mobile phone 10 is used as the target network device, and the network devices 02 to 05 not accessed by the mobile phone 10 are used as associated network devices.

Furthermore, when the user moves with the mobile phone 10 to the position 10B, the network device 01 is outside the Wi-Fi scanning area 10B1 of the mobile phone 10, that is, the mobile phone 10 is disconnected from the network device 01, and after the mobile phone 10 disconnects from the Wi-Fi network provided by the network device 01, the network device information B obtained by the mobile phone 10 at the position 10B through the full channel scanning is recorded. At this time, the network device information B includes network devices 06 and 07, and the network device 01 that is disconnected after the mobile phone 10 is connected is used as the target network device, and the network devices 06 and 07 that the mobile phone 10 is not connected to are used as the associated network devices.

In some embodiments, it can be understood that the above-mentioned position 10A is used as the living room of the user's residence, the position 10B is used as the bedroom bathroom of the user's residence, and the network device 01 is placed in the living room by the user as a wireless router. Then when the user carries the mobile phone 10 in the living room, due to the short distance, the user can scan and access the Wi-Fi network provided by the network device 01. At the same time, when the mobile phone 10 scans and accesses the network device 01, it also scans the neighbor's network devices, such as network devices 02, 03, 04 and 05; after the user carries the mobile phone 10 to the bedroom bathroom, the bedroom bathroom is far away from the network device 01, and the network device 01 cannot be scanned, that is, the mobile phone 10 is disconnected from the Wi-Fi network provided by the network device 01, so that the user cannot access the Wi-Fi network provided by the network device 01 in the bedroom bathroom, but at the same time, the mobile phone 10 can scan other neighbor's network devices at position 10B, such as network devices 06 and 07.

In some embodiments, the network device information A and the network device information B may be combined based on the fact that the network device information A and the network device information B include the same target network device. Network device information A and network device information B are used to generate the same target network device Wi-Fi fingerprints included in the two. That is, the Wi-Fi fingerprint of the corresponding network device 01 is generated by recording the full channel scan results when the mobile phone 10 is connected to the network device 01 and the full channel scan results when the mobile phone 10 is disconnected from the network device 01. As shown in Figure 4, the Wi-Fi fingerprint corresponding to the network device 01 includes network devices 01 to 07, among which network device 01 is used as the target network device and network devices 02 to 07 are used as associated network devices.

In some embodiments, the Wi-Fi fingerprint of network device 01 can be updated by recording the full channel scanning results each time the mobile phone 10 accesses and disconnects the network device 01. It can be understood that, as shown in FIG4, after the mobile phone 10 generates the Wi-Fi fingerprint of the corresponding network device 01 based on network devices 01 to 07, the mobile phone 10 may also scan other network devices, such as network devices 08 and 09, when it subsequently re-accesses and disconnects the network device 01. Then, when the mobile phone 10 subsequently re-accesses and disconnects the network device 01, network devices 08 and 09 can be used as associated network devices and updated to the Wi-Fi fingerprint of the corresponding network device 01, so that the Wi-Fi fingerprint of the network device 01 includes network devices 01 to 09, thereby making the Wi-Fi fingerprint of the network device 01 more complete and improving the identification of the network device 01 through the Wi-Fi fingerprint.

In other embodiments, after the mobile phone 10 is connected to the network device 01, the Wi-Fi fingerprint can be updated by periodically collecting the full channel scan results when the mobile phone 10 is connected to the network device 01. For example, after the mobile phone 10 is connected to the network device 01, the mobile phone 10 performs a full channel scan every half an hour or fifteen minutes, and updates the Wi-Fi fingerprint of the network device 01 based on the scan results.

In some embodiments, the mobile phone 10 can use multiple network devices that have been historically connected as different target network devices of the mobile phone 10; or the mobile phone 10 can also use one or more network devices that have been accessed more than a preset number of times among the multiple network devices that have been historically connected as the target network devices of the mobile phone 10, so that the target network device can represent the network device that the user frequently connects to; or the user can also customize the selection of any one or more network devices from the multiple network devices that have been historically connected as the target network device of the mobile phone 10, so that the target network device meets the user's personalized needs, without specific limitation.

In some embodiments, the user can upload the Wi-Fi fingerprint to a cloud server, and the user can share the Wi-Fi fingerprint to other terminal devices of the user through the cloud server, so that the user can also use the Wi-Fi fingerprint when using other terminal devices besides mobile phone 10; or different users can upload the obtained Wi-Fi fingerprint to the cloud server, and the cloud server can classify each Wi-Fi fingerprint based on the Media Access Control (MAC) address of the network device in the Wi-Fi fingerprint, and integrate the Wi-Fi fingerprint for network device 01, so that the Wi-Fi fingerprint of network device 01 is more complete, thereby improving the identification of network device 01 based on the Wi-Fi fingerprint.

In some embodiments, multiple associated network devices in a Wi-Fi fingerprint may be filtered and screened. For example, if the geographical locations of the multiple associated network devices are similar, for example, the signal strengths (Received Signal Strength Indication, RSSI) of the detection response frames received by the mobile phone 10 at the same location from the multiple associated network devices are the same or similar, then any one or a preset number of associated network devices may be retained from the multiple associated network devices to improve the uniqueness of each associated network device in the Wi-Fi fingerprint. While ensuring the accuracy of the Wi-Fi fingerprint in identifying the target network device, the data volume of the Wi-Fi fingerprint may be reduced, thereby improving the efficiency of users downloading the Wi-Fi fingerprint from the cloud server.

Some embodiments of the present application are explained below in conjunction with the scenario of the Wi-Fi fingerprint generation process shown in FIG. 4 .

FIG. 5A shows a flowchart of a wireless communication method according to some embodiments of the present application, which is applied to a mobile phone 10 and specifically includes the following steps:

S501: Detect the Wi-Fi connection mode of the mobile phone 10.

In some embodiments, whether the mobile phone 10 needs to initiate a Wi-Fi scan may be determined by detecting the Wi-Fi connection mode of the mobile phone 10 .

For example, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is connected, it means that the mobile phone 10 has been connected to the Wi-Fi network, and there is no need to initiate a Wi-Fi scan, jump to step S501A, and the process ends; or for example, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is not connected, it means that the mobile phone 10 is not connected to the Wi-Fi network, and a Wi-Fi scan needs to be initiated, jump to step S502.

S502: Acquire the channel set of the mobile phone 10, clear the scanning times of each scanning channel in the channel set, and then control the mobile phone 10 to perform full channel scanning through cycle 001.

In some embodiments, in combination with FIG. 4 above, as shown in FIG. 5B , when mobile phone 10 is located at position 10A, the Wi-Fi scanning area of mobile phone 10 is area 10A1; when mobile phone 10 is located at position 10B, the Wi-Fi scanning area of mobile phone 10 is area 10B1; when mobile phone 10 is located at position 10C, the Wi-Fi scanning area of mobile phone 10 is area 10C1; when mobile phone 10 is located at position 10D, the Wi-Fi scanning area of mobile phone 10 is area 10D1; network device 01 is the target network device of mobile phone 10.

Among them, network device 01 is a network device that mobile phone 10 has accessed in the past, and mobile phone 10 stores authentication password information for connecting to network device 01; when mobile phone 10 scans network device 01, mobile phone 10 can automatically obtain the password information of network device 01 and send it to the network. Device 01 initiates authentication, and the mobile phone 10 can automatically access the Wi-Fi network provided by network device 01 without the user entering a password. Network devices 02 to 09 are network devices that the mobile phone 10 has never accessed before. The mobile phone 10 does not store authentication password information and cannot automatically access the Wi-Fi networks provided by network devices 02 to 09. The user needs to manually enter the corresponding password information before initiating an authentication connection to the corresponding network device.

The following explanation is given by taking the case where the user cannot obtain the password information of the network devices 02 to 09 and the mobile phone 10 automatically connects to the Wi-Fi network after scanning the network device 01 as an example.

In some embodiments, as shown in FIG5B , when the user carries the mobile phone 10 to the position 10D, there is no network device that can be scanned around the mobile phone 10 , that is, the Wi-Fi connection mode of the mobile phone 10 is not connected.

Further, after determining that the Wi-Fi connection mode of the mobile phone 10 is not connected, the channel set of the mobile phone 10 is obtained. Among them, the channel set includes multiple scanning channels, and the multiple scanning channels can be a combination of any Wi-Fi channels that can be used in the above-mentioned 2.4GHz and 5GHz working frequency bands, or the multiple scanning channels can also be all Wi-Fi channels supported by the mobile phone 10 for Wi-Fi scanning, without specific restrictions. After controlling the mobile phone 10 to clear the scanning times of each scanning channel in the channel set, the mobile phone 10 is controlled to perform full channel scanning based on the channel set through cycle 001.

Among them, the scanning time interval between each Wi-Fi scan in cycle 001 is relatively long, for example, a Wi-Fi scan is performed every 60 seconds, because when the current mobile phone 10 is scanning through area 10D1 at position 10D, there is no network device that can be scanned, that is, the mobile phone 10 cannot connect to the Wi-Fi network, so using cycle 001 with a longer scanning interval to perform Wi-Fi scanning can reduce the scanning power consumption of the mobile phone 10. At the same time, since the mobile phone 10 is not connected to the Wi-Fi network at this time, the full channel scanning method in cycle 001 can improve the efficiency of the mobile phone 10 scanning network devices.

In some embodiments, when the mobile phone 10 finds a network device through full channel scanning in step S502, and the network device is a network device that the mobile phone 10 has historically connected to, such as when the network device 01 is scanned, it means that the mobile phone 10 matches the target network device, and the mobile phone 10 can automatically connect to the Wi-Fi network provided by the network device 01, that is, jump to step S502A.

In other embodiments, when the mobile phone 10 finds a network device through full channel scanning in step S502, and the network device is a network device that the mobile phone 10 has not connected to in history, such as when the network device 01 is not scanned, it means that the mobile phone 10 does not match the target network device, and jumps to step S503.

S503: Obtain a feature information table of the mobile phone 10, and match the scanning result of the full channel scan with the feature information table.

In some embodiments, as shown in FIG5B , when the user carries the mobile phone 10 and moves to position 10C, the mobile phone 10 acquires network devices, such as network devices 03, 05, 08, and 09, through full-channel scanning, and uses each scanned network device as a scanning result of the full-channel scanning, which is then matched with the feature information table.

In some embodiments, the Wi-Fi fingerprints corresponding to different target network devices can be determined by collecting the full channel scanning results when the mobile phone 10 historically accesses and disconnects the target network device. The specific determination process can be seen in Figure 4 above. For example, the Wi-Fi fingerprint corresponding to network device 01 includes at least one target network device as network device 01, and multiple associated network devices as network devices 02 to 07, which will not be described in detail here.

Furthermore, based on the Wi-Fi fingerprint, in combination with the Wi-Fi channel through which the mobile phone 10 accesses the target network device, a feature information table corresponding to the target network device is generated.

For example, as shown in FIG5C , the characteristic information table 50 includes the MAC address, target channel, Wi-Fi fingerprint and connection status of the target network device. Among them, when the target network device corresponding to the mobile phone 10 is the network device 01, the MAC address of the target network device is used to indicate the MAC address of the network device 01; the target channel is used to indicate the Wi-Fi channel through which the mobile phone 10 accesses the network device 01; the Wi-Fi fingerprint is used to indicate the MAC addresses of multiple network devices collected when the mobile phone 10 accesses and disconnects the network device 01, such as the MAC addresses of network devices 01 to 07, and the MAC address of the network device 01 currently accessed by the mobile phone 10 is used as the MAC address of the target network device; the connection status is used to indicate that the mobile phone 10 accesses or disconnects the network device 01, such as 1 indicates that the mobile phone 10 accesses the network device 01, and 0 indicates that the mobile phone 10 is disconnected from the network device 01.

Furthermore, after the mobile phone 10 obtains the scanning results of the network devices 03, 05, 08 and 09, the scanning results are matched with the feature information table.

In some embodiments, when the MAC addresses of multiple network devices in the scan result are not the same as the MAC addresses of multiple associated network devices in the Wi-Fi fingerprint, it is determined that the scan result does not match the Wi-Fi fingerprint, and the process jumps to step S502. It can be understood that when the scan result does not match the Wi-Fi fingerprint at all, it means that there is no target network device that has been historically connected around the current location of the mobile phone 10, and the mobile phone 10 cannot automatically access the Wi-Fi network, so the Wi-Fi scan is performed using the cycle 001 with a longer interval scanning time, thereby reducing the scanning power consumption of the mobile phone 10.

In other embodiments, when the MAC addresses of multiple network devices in the scan result are partially identical to the MAC addresses of multiple associated network devices in the Wi-Fi fingerprint, it is determined that the scan result matches the Wi-Fi fingerprint, and the process jumps to step S504.

S504: Acquire the target channel from the feature information table, and control the mobile phone 10 to perform partial channel scanning based on the target channel and through cycle 002.

In some embodiments, since the Wi-Fi fingerprint is a fingerprint collected when the mobile phone 10 historically accesses the target network device, the Wi-Fi fingerprint can be used to identify the location of the mobile phone 10 when it historically accesses the target network device. When the MAC addresses of multiple network devices in the scan result are partially the same as the MAC addresses of multiple associated network devices in the Wi-Fi fingerprint, if the MAC addresses of any one or more network devices in the scan result can be queried from the Wi-Fi fingerprint, it means that the mobile phone 10 is close to the location when it historically accessed the target network device, and the user carrying the mobile phone 10 may be moving in a direction close to the target network device.

Furthermore, the mobile phone 10 obtains the target channel of the target network device corresponding to the matching Wi-Fi fingerprint from the feature information table, and controls the mobile phone 10 to switch from full-channel scanning to a single-channel scanning method based on the target channel, thereby reducing scanning power consumption and ensuring scanning and searching for the target network device. At the same time, after the mobile phone 10 switches to single-channel scanning, the interval scanning time can be shortened. Relative to cycle 001, scanning is performed through cycle 002 with a shorter interval scanning time, for example, a Wi-Fi scan is performed every 20 seconds, thereby increasing the speed at which the mobile phone 10 connects back to the Wi-Fi network provided by the target network device, thereby improving the user experience.

In some embodiments, if the mobile phone 10 matches the Wi-Fi fingerprints of multiple target network devices, partial channel scanning can be performed based on multiple target channels corresponding to the multiple target network devices. It can be understood that after determining that the scan result matches the Wi-Fi fingerprint, the target network device is determined by the matched Wi-Fi fingerprint, such as querying from the Wi-Fi fingerprint which network devices are network devices that the mobile phone 10 has accessed in the past, taking the network devices that have been accessed in the past as target network devices, and switching from full channel scanning to single channel scanning or partial channel scanning through the target channel recorded when the target network device was historically accessed.

The following explanation is given by taking the scanning result of the full channel scan of the mobile phone 10 matching the Wi-Fi fingerprint of the network device 01, and the mobile phone 10 switching from the full channel scan to the single channel scan mode of the target channel of the network device 01 that the mobile phone 10 historically accessed as an example.

For example, as shown in 5B, the user carries mobile phone 10 at position 10C, so that after the full channel scan result of mobile phone 10 matches the Wi-Fi fingerprint, mobile phone 10 obtains the target channel of the target network device corresponding to the Wi-Fi fingerprint, such as the target channel of network device 01, performs a single channel scan based on the target channel, shortens the interval scanning time relative to period 001, and performs Wi-Fi scanning through period 002 with a shorter interval scanning time.

In some embodiments, after the user carries the mobile phone 10 and moves from the position 10C to the position 10A, the mobile phone 10 scans the network device 01, and the mobile phone 10 can automatically access the Wi-Fi network provided by the network device 01, and then jumps to step S502A.

In other embodiments, if the user carries the mobile phone 10 and moves from position 10C in a direction away from position 10A, such as from position 10C to position 10D, the mobile phone 10 cannot scan the network device 01, and the mobile phone 10 cannot automatically connect to the Wi-Fi network provided by the network device 01, then jump to step S505.

S505: Record the number of scans of the target channel, and determine whether the number of scans of the target channel exceeds a preset number.

In some embodiments, the scanning cycle and scanning channel of the mobile phone 10 can be switched according to the scanning times of the target channel.

For example, when the mobile phone 10 fails to scan the network device 01 and the target channel is scanned less than the preset number of times, it may indicate that the user carrying the mobile phone 10 may be moving towards the direction close to the network device 01, and the process jumps to step S504, where the mobile phone 10 continues to use the target channel and cycle 002 for Wi-Fi scanning.

For another example, when the mobile phone 10 fails to scan the network device 01 and the number of scans of the target channel exceeds the preset number, it indicates that the user carrying the mobile phone 10 may move in a direction away from the signal of the network device 01, and thus the mobile phone 10 cannot automatically access the Wi-Fi network provided by the network device 01 in a short time, and then jumps to step S502. The mobile phone 10 switches from single-channel scanning to full-channel scanning to improve the efficiency of the mobile phone 10 in scanning the network device. At the same time, the mobile phone 10 switches from the cycle 002 with a shorter interval scanning time to the cycle 001 with a longer interval scanning time to scan, thereby reducing the scanning power consumption of the mobile phone 10.

In some embodiments, as shown in FIG. 5B , it can be understood that the above-mentioned position 10A is used as the living room of the user's residence, the position 10C is used as the corridor of the user's residence, the position 10D is used as the community of the user's residence, and the network device 01 is placed in the living room by the user as a wireless router.

When the user carries the mobile phone 10 into the residential area, the mobile phone 10 cannot scan the network device 01 because it is far away from the living room. The mobile phone 10 uses the period 001 with a longer interval scanning time to perform a full-channel Wi-Fi scan to ensure that the network device can be scanned. When the user carries the mobile phone 10 to approach the living room and enters the corridor of the residence, the mobile phone 10 scans the network device and matches the Wi-Fi fingerprint of the network device 01, indicating that the user may be approaching the living room with the mobile phone 10, so that the mobile phone 10 switches from the period 001 with a longer interval scanning time to the period 002 with a shorter interval scanning time, increases the scanning frequency, and performs a single-channel scan based on the Wi-Fi channel when the network device 01 was accessed historically. Reduce scanning power consumption; before the user goes upstairs or enters the living room, because the mobile phone 10 adopts a high-frequency scanning method for the access channel of the network device 01, when the mobile phone 10 enters the signal coverage area of the network device 01, the mobile phone 10 can immediately scan the network device 01 and automatically connect to the Wi-Fi network provided by the network device 01, thereby improving the reconnection speed of the Wi-Fi network of the mobile phone 10, thereby meeting the user's networking needs for the mobile phone 10.

FIG5D shows a schematic diagram of a process of generating a feature information table according to some embodiments of the present application, which specifically includes the following steps:

S51A: The mobile phone 10 accesses the Wi-Fi network.

In some embodiments, when it is detected that the mobile phone 10 is connected to a Wi-Fi network, a determination is made as to whether the mobile phone needs to generate a feature information table, and a determination result A is generated.

S51B: The mobile phone 10 disconnects from the Wi-Fi network.

In some embodiments, when it is detected that the mobile phone 10 is disconnected from the Wi-Fi network, a determination is made as to whether the mobile phone needs to generate a feature information table, and a determination result B is generated.

S52: Determine whether to generate a feature information table.

In some embodiments, the mobile phone 10 can prompt the user whether it is necessary to generate a feature information table through an information pop-up window when connecting to a Wi-Fi network or disconnecting from a Wi-Fi network, and the user can then determine whether it is necessary to generate a feature information table through the information pop-up window. For example, when the mobile phone 10 is connected to a Wi-Fi network, the mobile phone 10 detects that the user determines through the information pop-up window that a feature information table needs to be generated, then the judgment result A is that the feature information table needs to be generated; or for example, when the mobile phone 10 is connected to a Wi-Fi network, the mobile phone 10 detects that the user determines through the information pop-up window that a feature information table does not need to be generated, then the judgment result A is that the feature information table does not need to be generated. Among them, the judgment result B is the same as the judgment result A, and will not be repeated here.

In some embodiments, when any one of the judgment results A and B requires generating a feature information table, jump to step S53; when both the judgment results A and B do not require generating a feature information table, jump to step S57, and the process ends.

S53: Collect Wi-Fi fingerprints of all-channel scanning by the mobile phone 10 .

In some embodiments, since the time when the mobile phone 10 accesses and disconnects from the Wi-Fi network is different, that is, any one of the judgment results A and B requires the generation of a feature information table, the process can jump to step S53 separately.

For example, when the mobile phone 10 accesses the Wi-Fi network, the judgment result A is that the feature information table needs to be generated, and the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected when the mobile phone 10 accesses the Wi-Fi network. Further, when the mobile phone 10 disconnects the Wi-Fi network, the judgment result B is that the feature information table needs to be generated, and the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected when the mobile phone 10 disconnects the Wi-Fi network. That is, when the mobile phone 10 accesses or disconnects the Wi-Fi network, the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected.

For another example, when the mobile phone 10 is connected to a Wi-Fi network, the judgment result A is that it is not necessary to generate a feature information table, and the Wi-Fi fingerprint is not collected when the mobile phone 10 is connected to the Wi-Fi network. Further, when the mobile phone 10 is disconnected from the Wi-Fi network, the judgment result B is that it is necessary to generate a feature information table, and the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected when the mobile phone 10 is disconnected from the Wi-Fi network. That is, the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected only when the mobile phone 10 is disconnected from the Wi-Fi network.

Or for example, when the mobile phone 10 accesses the Wi-Fi network, the judgment result A is that the feature information table needs to be generated, and the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected when the mobile phone 10 accesses the Wi-Fi network. Further, when the mobile phone 10 disconnects the Wi-Fi network, the judgment result B is that the feature information table does not need to be generated, and the Wi-Fi fingerprint is not collected when the mobile phone 10 disconnects the Wi-Fi network. That is, the Wi-Fi fingerprint of the full channel scan of the mobile phone 10 is collected only when the mobile phone 10 accesses the Wi-Fi network.

For the specific collection process, please refer to the Wi-Fi fingerprint collection process described in FIG. 4 above, which will not be described in detail here.

S54: Collect the MAC address and target channel of the target network device for the mobile phone 10 to access the Wi-Fi network.

In some embodiments, the MAC address of the network device corresponding to the Wi-Fi network to which the mobile phone 10 accesses is used as the MAC address of the target network device, and the Wi-Fi channel of the corresponding network device scanned before the mobile phone 10 accesses the Wi-Fi network is used as the target channel.

S55: Generate a feature information table based on the collection results.

In some embodiments, a feature information table is generated based on the Wi-Fi fingerprint, the MAC address of the target network device, the target channel, and the state of the mobile phone 10 when it is connected to or disconnected from the Wi-Fi network. For example, the feature information table 50 in step S503.

S56: Store the feature information table in the cloud server.

In some embodiments, the feature information table is transmitted to a cloud server so that the user can share the feature information table to other terminal devices of the user through the cloud server, so that the user can also use the feature information table when using other terminal devices besides mobile phone 10.

S57: End. After the storage of the characteristic information table is completed, or the result of any judgment that the mobile phone 10 is connected to or disconnected from the Wi-Fi network is not When it is necessary to generate the feature information table, the process of generating the feature information table ends.

In other embodiments, when the mobile phone 10 accesses or disconnects from the Wi-Fi network provided by the target network device, the mobile phone 10 can simultaneously collect the Wi-Fi fingerprint and cell identification (Cellular Identity, cell ID) information of the mobile phone 10, and load the correspondence between the cell identification set, the Wi-Fi fingerprint and the target network device currently accessed by the mobile phone 10 into the feature information table, so that the mobile phone 10 can further switch the scanning cycle of the mobile phone 10 by detecting the change of the cell identification.

The following is an explanation of other embodiments of the present application in combination with the method shown in FIG. 5A and the scenario shown in FIG. 5B .

FIG6A shows a flowchart of another wireless communication method according to some embodiments of the present application, which is applied to a mobile phone 10 and specifically includes the following steps:

S601: Detect the Wi-Fi connection mode of the mobile phone 10.

For example, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is connected, it means that the mobile phone 10 has been connected to the Wi-Fi network, and there is no need to initiate a Wi-Fi scan, jump to step S601A, and the process ends; or for example, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is not connected, it means that the mobile phone 10 is not connected to the Wi-Fi network, and a Wi-Fi scan needs to be initiated, jump to step S602.

S602: Detect whether the cell ID of the mobile phone 10 has changed.

In some embodiments, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is not connected and the cell identifier of the mobile phone 10 has not changed, it means that the mobile phone 10 may stay at the location when the Wi-Fi connection mode is not connected, and jump to step S602A.

S602A: Acquire the channel set of the mobile phone 10 and control the mobile phone 10 to perform full channel scanning through cycle 003.

In some embodiments, for example, when the mobile phone 10 stays at the position 10D as shown in FIG. 5B and there is no network device that can be scanned around the mobile phone 10, the channel set of the mobile phone 10 is obtained and the mobile phone 10 is controlled to perform a full channel scan based on the channel set through period 003.

Among them, cycle 003 is relative to cycle 002 and cycle 001 in FIG. 5A above, and the scanning cycle relationship of each cycle is cycle 003>cycle 001>cycle 002. It can be understood that the interval scanning time of cycle 003 is the longest. For example, a Wi-Fi scan is performed every 120 seconds. This is because the mobile phone 10 is not currently connected to the Wi-Fi network, and the cell identification of the mobile phone 10 has not changed, indicating that the mobile phone 10 may stay at the location where the Wi-Fi network is not connected, that is, the mobile phone 10 cannot connect to the Wi-Fi network. Therefore, using the cycle 003 with the longest interval scanning time for Wi-Fi scanning can reduce the scanning power consumption of the mobile phone 10. At the same time, since the mobile phone 10 is not connected to the Wi-Fi network at this time, the full channel scanning method can improve the efficiency of the mobile phone 10 scanning network devices.

In other embodiments, when it is detected that the Wi-Fi connection mode of the mobile phone 10 is not connected and the cell identifier of the mobile phone 10 changes, it means that the user may move the mobile phone 10 away from the location when the Wi-Fi connection mode is not connected, and jump to step S602B.

S602B: Obtain a feature information table of the mobile phone 10, and match the change result of the cell identifier with the feature information table.

In some embodiments, when the mobile phone 10 accesses or disconnects from the Wi-Fi network provided by the target network device, a feature information table corresponding to the target network device is generated by collecting the Wi-Fi fingerprint and cell identification set of the mobile phone 10 .

For example, as shown in FIG6B , the characteristic information table 60 includes the MAC address of the target network device, the target channel, the cell identifier set, the Wi-Fi fingerprint, and the connection state. Among them, when the target network device corresponding to the mobile phone 10 is the network device 01, the MAC address of the target network device is used to indicate the MAC address of the network device 01; the target channel is used to indicate the Wi-Fi channel of the mobile phone 10 to access the network device 01; the cell identifier set is used to indicate the multiple cell identifiers collected when the mobile phone 10 accesses and disconnects the network device 01, such as the cell identifiers 1A, 1B, and 1C; the Wi-Fi fingerprint is used to indicate the MAC addresses of the multiple network devices collected when the mobile phone 10 accesses and disconnects the network device 01, such as the MAC addresses of the network devices 01 to 07, and the MAC address of the network device 01 currently connected by the mobile phone 10 is used as the MAC address of the target network device; the connection state is used to indicate that the mobile phone 10 accesses or disconnects the network device 01, such as 1 indicates that the mobile phone 10 accesses the network device 01, and 0 indicates that the mobile phone 10 is disconnected from the network device 01.

In some embodiments, in step S602B, as shown in FIG5B , the user carries the mobile phone 10 and moves from position 10D to position 10C, and the mobile phone changes from cell identifier 1D to cell identifier 1C, that is, the change result is cell identifier 1C, and the change result matches the cell identifier set in the feature information table, indicating that there may be network devices that can be scanned around the mobile phone 10, and jumps to step S603, that is, obtaining the channel set of the mobile phone 10, and after clearing the scanning times of each scanning channel in the channel set, controlling the mobile phone 10 to perform a full channel scan through cycle 001, thereby improving the efficiency of the mobile phone 10 in scanning network devices and ensuring the efficiency of the mobile phone 10 in scanning network devices.

In some embodiments, in step S603, when the mobile phone 10 scans a network device through all channels and the network device is a network device that the mobile phone 10 has historically connected to, such as when the network device 01 is scanned, it indicates that the mobile phone 10 matches the target network device and jumps to step S603A, that is, the mobile phone 10 can automatically access the Wi-Fi network provided by the network device 01.

In some embodiments, in step S603, the mobile phone 10 scans the network device through all channels, and the network device is the mobile phone 10 When the network device has not been connected in the history, such as when the network device 01 is not scanned, it means that the mobile phone 10 does not match the target network device, and jumps to step S604, that is, obtaining the feature information table of the mobile phone 10, and matching the scanning result of the full channel scan with the feature information table.

In some embodiments, in step S604, when the MAC addresses of multiple network devices in the scan results of the full channel scan of the mobile phone 10 are partially identical to the MAC addresses of multiple associated network devices in the Wi-Fi fingerprint, it is determined that the scan result matches the Wi-Fi fingerprint, and the process jumps to step S605, that is, obtaining the target channel from the feature information table, and controlling the mobile phone 10 to perform partial channel scanning based on the target channel and through cycle 002.

In some embodiments, in step S605, as shown in Figure 5B, after the user carries the mobile phone 10 and moves from position 10C to position 10A, the mobile phone 10 scans the network device 01 and jumps to step S603A. The mobile phone 10 can automatically access the Wi-Fi network provided by the network device 01.

In some embodiments, in step S605, as shown in FIG5B , if the user carries the mobile phone 10 and moves from position 10C in a direction away from position 10A, such as from position 10C to position 10D, the mobile phone 10 cannot scan the network device 01, and the mobile phone 10 cannot automatically access the Wi-Fi network provided by the network device 01, then the process jumps to step S606, i.e., recording the number of scans of the target channel and determining whether the number of scans of the target channel exceeds a preset number.

In some embodiments, in step S606, when the mobile phone 10 fails to scan the network device 01 and the number of scans of the target channel does not exceed the preset number, it may indicate that the user carrying the mobile phone 10 may be moving in a direction close to the network device 01, and the process jumps to step S605, and the mobile phone 10 continues to use the target channel and cycle 002 for Wi-Fi scanning.

In other embodiments, in step S604, when the MAC addresses of multiple network devices in the scan result are all different from the MAC addresses of multiple associated network devices in the Wi-Fi fingerprint, it is determined that the scan result does not match the Wi-Fi fingerprint, and the process jumps to step S607.

In other embodiments, in step S606, when the mobile phone 10 fails to scan the network device 01 and the number of scans of the target channel exceeds a preset number, it indicates that the user carrying the mobile phone 10 may be moving in a direction away from the signal of the network device 01, and thus the mobile phone 10 cannot automatically access the Wi-Fi network provided by the network device 01 in a short period of time, and the process jumps to step S607.

S607: Detect the status mode of the mobile phone 10.

In some embodiments, when it is detected that the state mode of the mobile phone 10 is a mobile state, jump to step S603, that is, obtain the channel set of the mobile phone 10, clear the scanning times of each scanning channel in the channel set, and control the mobile phone 10 to perform a full channel scan through cycle 001.

It can be understood that although in step S604, the scanning result of mobile phone 10 does not match the Wi-Fi fingerprint; however, since in step S602B, the change result of the cell identifier of mobile phone 10 matches the cell identifier set; and mobile phone 10 is in a mobile state, mobile phone 10 may obtain other network devices in the mobile state, and then update the scanning result, so that the scanning result may match the Wi-Fi fingerprint or the target network device, that is, mobile phone 10 can continue to perform full-channel scanning through cycle 001, and the interval scanning time of cycle 001 is less than the interval scanning time of cycle 003. Mobile phone 10 uses the full-channel scanning method of cycle 001, which can improve the efficiency of mobile phone 10 scanning network devices.

In other embodiments, when it is detected that the state mode of the mobile phone 10 is a stationary state, the process jumps to step S602A, that is, obtaining the channel combination of the mobile phone 10 and controlling the mobile phone 10 to perform a full channel scan through cycle 003.

It can be understood that in step S604, the scanning result of the mobile phone 10 does not match the Wi-Fi fingerprint, and the mobile phone 10 is in a stationary state, that is, the mobile phone 10 stays at a position where the scanning result does not match the Wi-Fi fingerprint, that is, the mobile phone 10 cannot connect to the Wi-Fi network, so the Wi-Fi scan is performed using the cycle 003 with the longest interval scanning time, which can reduce the scanning power consumption of the mobile phone 10. At the same time, since the mobile phone 10 is not connected to the Wi-Fi network at this time, the full channel scanning method can improve the efficiency of the mobile phone 10 scanning network devices.

In some embodiments, in step S602A, if it is detected that the mobile phone 10 switches from a stationary state to a moving state, the process jumps to step S602, that is, detecting whether the cell identifier of the mobile phone 10 changes.

It can be understood that when the cell identifier does not change, or the result of the cell change does not match the cell identifier set, or the full channel scan result does not match the Wi-Fi fingerprint and the mobile phone 10 is in a stationary state, or the number of scans of the target channel exceeds the preset number of times and the mobile phone 10 is in a stationary state and the mobile phone 10 cannot connect to the Wi-Fi network, the mobile phone 10 uses the cycle 003 with the longest interval scanning time to perform Wi-Fi scanning. If it is detected that the mobile phone 10 switches from a stationary state to a mobile state under the above circumstances, it means that the user may carry the mobile phone 10 away from the location where the Wi-Fi network cannot be connected, and the mobile phone 10 may obtain other cell identifiers in the mobile state, then re-detect whether the cell identifier of the mobile phone 10 has changed, and jump to step S602.

It can be understood that, compared with the process shown in FIG. 5A , the process shown in FIG. 6A adds the step of detecting the cell identification and the state mode of the mobile phone 10, and switching the scanning cycle of the mobile phone 10 based on the result of the detection, so that the mobile phone 10 can switch between cycles 001 to 003. At the same time, as long as the mobile phone 10 is in the power-on state, the cell identifiers of each signal base station in the signal area can be obtained, that is, the acquisition of the cell identifier by the mobile phone 10 will not increase the power consumption of the mobile phone 10. Moreover, in cycles 001 to 003, the interval scanning time of cycle 003 is the longest. It can be understood that the detection of the cell identifier allows the mobile phone 10 to switch between cycles 001 to 003, which can effectively reduce the scanning power consumption of the mobile phone 10. Moreover, during the reconnection scanning process, the mobile phone 10 matches multiple features in the feature information table, so that the mobile phone 10 switches between the full channel scanning mode, the single channel or the multi-channel scanning mode while switching between cycles 001 to 003, further reducing the scanning power consumption of the mobile phone 10, and improving the efficiency of the mobile phone 10 scanning the network equipment through the switching of the cycle.

It can be understood that the detection of the cell identification and status mode of the mobile phone 10 in the flowchart shown in Figure 6A above is only an example. In other embodiments, the detection of the cell identification and status mode of the mobile phone 10 can also be applied to any one of the scenarios in Figures 1 to 5D above or a combination of any multiple scenarios, without specific limitation.

It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present application is only a schematic illustration and does not constitute a structural limitation on the mobile phone 10. In other embodiments of the present application, the mobile phone 10 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 may receive charging input from a wired charger through the USB interface 130.

In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

The modem processor may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and may be provided in the same device as the mobile communication module 150 or other functional modules.

The mobile phone 10 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor. ISP is used to process the data fed back by camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on the noise, brightness and skin color of the image. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, ISP can be set in camera 193.

The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the mobile phone 10 may include 1 or N cameras 193, where N is a positive integer greater than 1.

The digital signal processor is used to process digital signals. In addition to processing digital image signals, it can also process other digital signals.

Video codecs are used to compress or decompress digital videos. Mobile phone 10 may support one or more video codecs. Thus, mobile phone 10 may play or record videos in a variety of coding formats, such as moving picture experts group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

NPU is a neural network (NN) computing processor. It can quickly process input information by drawing on the structure of biological neural networks, such as the transmission mode between neurons in the human brain, and can also continuously self-learn. NPU can realize applications such as intelligent cognition of the mobile phone 10, such as image recognition, face recognition, voice recognition, text understanding, etc.

The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the terminal device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music and videos can be stored in the external memory card.

The internal memory 121 may be used to store computer executable program codes, which may include instructions. 121 may include a program storage area and a data storage area. The program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the mobile phone 10 (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 110 executes various functional applications and data processing of the mobile phone 10 by running instructions stored in the internal memory 121 and/or instructions stored in a memory provided in the processor. For example, in some embodiments, the internal memory 121 may be used to temporarily store instructions of the wireless communication method provided in the aforementioned embodiments.

The mobile phone 10 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the earphone interface 170D, and the application processor.

The SIM card interface 195 is used to connect a SIM card.
